Current Methods to Sow Seeds

The current methods used by small-scale farmers to sow seeds are low cost but may be laborious or unattainable for certain households. Current sowing methods involve 2-3 people working together utilizing very few tools: usually a man will steer the cattle so they can create grooves in the soil while one or two women follow behind and drop the seeds into the grooves. However, as men in more rural communities are often unavailable as they have other responsibilities such as migrant work to generate income, they may not be able to help the women steer the cattle. In certain cultures, there is a certain taboo against women handling cattle (Meyer-Rochow, 2009), and therefore they would be unable to sow seeds if a male is not present to help them. It is important while conducting research on low-cost sowing tools to find tools that are durable, lightweight, and the correct height for women for them to be capable of sowing seeds independently. It is also important that these tools are adjustable for varying seed sizes, low-cost and able to be shared amongst different households to share cost.

Low-Cost Tools to Sow Seeds

Seed sowing tools that low-cost, efficient, and durable tools are crucial for subsistence farmers.

•Electric sowing machines: An efficient option for a seed sowing tool is a motorized seed sowing machine.

Use of the Fanning Mill to Remove Diseased Seed

Smallholder farmers often face the difficulty of diseased crops. Bunts and smuts are a concern for these farmers in Africa as they can greatly reduce yield of a crop and its value and marketability if not dealt with correctly (Agricultural Research Council, n.d.). There is a seed treatment process that is available to prevent bunts and smuts (Agricultural Research Council, n.d.), however, farmers looking to save money or farmers who cannot afford to have their seeds treated may have their crops infected. These diseases can be dealt with using a fanning mill. Bunts and smut balls can be removed during the fanning process along with the chaff and anything else unwanted (Garlough, 2021). In addition to the balls being removed, diseased seeds will be blown, filtered, and separated in the milling process as well.

Cost / Benefit and Critical Analysis

A fanning mill would prove to be very beneficial to smallholder farmers. It can help farmers save money and avoid losing crops to disease by getting rid of diseased seeds in the milling process. The price of a fanning mill can still be considerable for smallholder farmers in developing countries. Despite fanning mills being expensive for farmers, there are opportunities for them to obtain financial aid. A few of these options are purchasing through a farmer cooperative or a women’s farmer group or making use of a local fee-for-service entrepreneur who will sell the use of their fanning mill. Farmers could also make use of 50:50 cost sharing with their government or seek out a micro-loan program to assist in the purchase of a fanning mill. It is possible that a community of farmers could all split the cost of one of these machines. This would allow many of the farmers within the community access to more efficient methods of cleaning seeds and benefit everyone. However, the heavy weight of these machines can make transportation to rural mountainous areas very difficult. Literacy is also a requirement as these machines require considerable training to operate effectively. Manuals must also be in the local language if they are to be of any use to the farmers.

The cost of fanning mills can be expensive for smallholder farmers. However, the benefits of using a fanning mill would be considerable as it would save crops from disease and save a lot of time that would have been used separating seeds using more traditional methods. On average, woman can winnow 10 – 30 kilograms of grain each day (Food and Agriculture Organization, n.d.), while a fanning mill can clean 500 kg of seed per hour with one operator (Sun Agro, n.d.). In one hour, a fanning mill can clean between 16 and 50 times more seeds than one woman can in a day. One hour of running the fanning mill could save 16 to 50 days of work for these women farmers. This is an incredible time saver and will allow these women to perform other tasks with their time.

Compared to traditional methods of cleaning seed, Figure 1 shows three different fan options. The winnowing fan, Option 1, is a manual fan attached to a crank that can be turned at various speeds to allow another person to clean the seeds. This could be a good option as it does not require waiting for winds strong/weak enough to clean seeds using natural winds (Benson, n.d.). However, it is a two-person job because one person must be operating the fan. By contrast, the small fanning mill (Option 2) is operated using a small crank that generates electricity to power the mill (Sun Agro, n.d.). It can be operated continuously and by a single person. It is a more expensive option, and it is unlikely that many smallholder farmers will be able to purchase one on their own. The last option (Option 3), the fanning mill, is a much larger and more expensive version of the small fanning mill. It is purely electric and can process 4 times the amount of grain as the latter (Meena Industries, n.d.). It is very unlikely that any individual farmer would be able to purchase one on their own.

The fanning mills shown are electric, however, there are options that do not require electricity that would allow farmers to cut down costs of these machines (Garlough, 2021). A manual fanning mill operating by a crank would cost less due to the mill having no electric motor or any electricity requirement for the machine to operate (Garlough, 2021). Furthermore, any expensive motor repairs could be avoided using a manual fanning mill (Garlough, 2021). The development of solar powered technology is much needed and would be massively beneficial in reducing operating costs. Additionally, fanning mills can also make use of a combustion engine as opposed to an electric engine. This would allow farmers who are no connected to a grid to uses powered fanning mills as well.
